Abstract
Summary
The paper considers the Shale strata of the Azov-Kuban Oligocene-Miocene generation-accumulation hydrocarbon system. The Maikop series in the study area is a hybrid phenomenon, including both oil and gas source properties and hydrocarbon accumulating complexes-natural reservoirs. The study of these objects allows us to conclude that organic porosity plays an important role in determining the total volume of the accumulated part of hydrocarbons in the oil and gas source strata. In dense immature kerogen, during oil formation, organic pores ("kerogen porosity") begin to form, which towards the end of the main oil formation zone form a coherent system that provides space for newly formed oil hydrocarbons.
